Angular Chart - loadingIndicator
When the UI component is bound to a remote data source, it can display a loading indicator while data is loading.
To enable the automatic loading indicator, set the enabled property to true.
The loading indicator's visibility is tied to the DataSource's load method: it appears when the method's execution starts and hides when the execution is complete. The Chart calls the method internally.
If you want to change the loading indicator's visibility, use the show property.
